This is what I ordered.
I‘m praying I got it right...
I would like to replace my current switch panel with a more modern looking one and with back lighting.
To anyone else looking at doing this...I just went through the dance over the past two weeks trying to decide a course of action.
As others have said, New Wire Marine for the win. I ended up not going to a custom panel due to the $$$ being better spent elsewhere (recovering my coaming bolsters and adding two removable cushions to livewell and fishbox tops trumped that).
For my ‘87 Gulfstream, the 16 switch panel blank is a direct replacement for the original. 10.75”L x 6.75” W if memory serves. I may have to shave it a hair, but it is within a 1/8” , and thinner than starboard, so should still allow my acrylic splashguard to still close.
Look at their stock blank sizes. I was going to use breakers in their own Blue Sea enclosure, but after toying with the sizes of the blank panels, ended up with them on the panel.
Adding switches, breakers, charger (lighter) holes, etc. changes the dimensions slightly. Have a look. You may be able to find a near perfect fit with CNC precision without having to fool with the starboard route. Now...if I can just figure out a DIY backlighting scheme.
